Question

Which has non integral bond o2+ , o2- , no , all of these?

Answer 1

no is the answer please

Answer 2

The correct option of the above question is (d), that is all of these ions have non-integral bonds.

Non Integral bond definition -

• Bond order is non-integral when the difference in the number of electrons in a molecular orbital and the number of electrons in an anti-molecular orbital is odd.

Bond order - The bond order is defined as half the difference between the number of electrons in bonding molecular orbitals (Nonbonding) and the number of electrons in the antibonding molecular orbital.

The bond order of O₂+

B.O for O₂+ = 1/2 × [10 – 5]

                   = 2.5

Hence bond order for O₂+ = 2.5

The bond order of O₂⁻¹ -

The number of bonding electrons is 8.

The number of antibonding electrons is 5.

Bond order = 1/2[8 – 5]

Bond order = 1/2[3]

Bond order = 1.5

Since the bond order of O₂⁺ is 2.5, and that of O₂⁻ is 1.5, and both are non-integral bonds. Hence all of these will be the correct option.
